Lora Cross feels so guilty about skipping her regular ab workout at the gym, but she is just so sick of doing crunches. She needs something more challenging and more intense to feel a deeper burn. She suggests to her friend Sablique that she could give her some hard belly punches to liven up her routine. But with every blow that Sablique lands on Lora’s rock hard abs, Lora gets more and more turned on. At the end when Lora’s abs are burning, Sablique uses Lora’s belly as a speed bag until she cums from the intensity and pressure.
